MILK-COOLER.

SFEQJIFIGATION forming part of Letters Batent No. 779,823, dated January 10, 1905. Application filed June 14,1904. Serial Eda-212,562.

To all whom it may concern:

Be it known that we, J 01in W. WALKUP and CHARLES W. WALKUP, citizens of the United States, and residents of Rosebud, countyof Falls, State of Texas, have invented certain new and useful Improvements in Milk-COOL ers, of which the following .is a specification. Our invention relates to devices for cooling milk, cream, and other liquids, and more especia'lly to such coolers wherein the liquid-is contained in open jars, bottles, &c., supported on shelves around which the air cooled, preferably by evaporation of moisture, is caused or permitted to freely circulate.

Our objects are to provide a cooler of the character indicated in which the shelves may be readily removed and replaced, whereby the device may be easily cleaned; to so construct and arrange the parts that the milk or other liquid, contained in suitable receptacles, may be easily and quickly placed upon the shelves and removed therefrom; to make the device of the'lightest possible weight consistent with the strength required .in use, so that it will not only be easy to handle in ordinary use, but will be cheap in manufacture and cost the least amount in freight or other charges for transportation, and, finally, to provide a device of this character which shall possess the fewest parts and simplest construction and be I thoroughly hygienic or capable of being so maintained with the slightest care.

With these ob ects in view our invention consists in the novel-construction of cooler and in the details thereof, as hereinafter described, with reference to the accompanying drawings, and more particularly pointed out in the claims hereto appended.

In the drawings, Figure 1 is a front elevation of a cooler embodying our invention with a part broken away, and Fig. 2 is a central vertical section of the main structure with certain parts in elevation.

' Referring now particularly to the drawings, in-which the same reference characters relate to the same or. corresponding parts in both views, it will be observed that we provide a bottom pan 1, having flaring sides orwalls 8 and supported upon suitable legs 2, secured thereto in any convenient way. As we preand the distance apart of the shelves.

fer to make all parts of'the device of galvanserve not only as braces to strengthen the structure, but as supports for the flat shelves 5, upon which the milk or other liquid is placed in jars, crooks, bottles, or other recep- 'tacles17. Mounted upon the upper ends of the tubular supports 3 is the top pan l2, and intermediate the top and bottom pans are the shelves 5, supported, as above indicated, on opposite cross rods or braces t. Each of the shelves is provided with downwardly-extending lips or flanges 7 adapted to partially surround or embrace one of the'braces or rods 4, and which, owing to the resiliency of the metal, exert sufiicient pressure upon the respective supports to retain-the shelf in position thereon and yet permit the same to be readily removed by simply grasping one of the flanges between the fingers and raising the edge of the shelf above the rod 4 and gently pushing the shelf outwardly or pulling it in such direction with the other hand. These lips or orshedding any water that may accumulate thereon onto the next-lower shelf and finally into the bottom pan 1, according to the batter or inclination. of the posts or supports 3 ()n the side of the shelf 5 are transverscly-extending and upwardly-turned flanges 6, which when the shelf is in position rest against adjacent supports 3, thereby affording an additional security to the shelf structure and adding strength thereto, such flanges being likewise resilient, and hence readily permitting removal of a shelf when desired. i

The top pan 12 .has vertical side walls and is provided with a central ventilating-opening surmounted bya guard-flange 15, which prevents any water from overflowing through flanges 7 also secure the purpose of directing I do - said opening onto the shelf below. This open-- eign matter from passing below.

ing is provided with a protecting wire-gauze netting 16, which prevents insects or any forof textile material, such as light cottonv fabric,incloses the structure from top to bottom,

so that there is no exposure of the milk or otherliquid while it. is being cooled. This cloth covering is preferablyin a single piece and so formed that its upper edge when in po-' sition will envelop the rim or flange of the pan 12 and extend down to-beimmersed in the wate'r'which is maintained therein through the medium of a reservoiror bucket 10, having a dr'ip-cock'll regulated so as to keep a cool and fresh supply of waterin the pan suificient to be absorbed by the cloth and spread thereover by capillary attraction. The

lower edge of the cloth is immersed in the water held in the bottom pan 1, so. that it not only receives water therefrom, but forms a water seal at this point to keep out insects, dust, dirt, &c. The cloth is held in place by any suitable means, and we have shown in the drawings a simple device for this purpose consisting of one or more sharpened studs or pins'l l, projecting-from the side of the pan 1 2 atithe top, and a similarpin 13, projecting from one'or more of the posts 3, the cloth being simply wrapped around the structure,

"with the edges adjusted as above defined and I the overlapping edges 19 impaled on said pins or studs.

The bottom pan 1 is provided with closable discharge-opening closed by a screw-cap 9, which isrenioved when desired to permit the water in the panto runout, so that fresh water may be supplied thereto.

With a device constructed according to our invention it will be observed that when the milk 'or other liquid containing receptacles are in place and the cooling liquid or water supplied to the top and bottom pans the cloth will become quickly moistened throughou tits area, v and as the moisture therein evaporates, which it does quickly in ordinary temperature and. umidity, the air circulating over and around the said milk, &c., being thereby cooled recools the same, and maintains A cloth 18,.

duces the temperature thereof, effectively it at a suitably low temperature.

While We have described a convenient form of our cooler, it is to be observed that various '1 changes may be made in the formand arrangement of the parts, inclination" of the posts,

proportions, &c., without'departing from the. spirit of our invention.

We claim as our invention 1. In a cooler for milk or other liquid, the combination of a bottom pan supported by legs, inclined posts extending upwardly from I said pan, cross-braces interposed between andin line with the pairs of said posts acting to brace the structure and as supports for shelves,

one or more removable fiat shelves of resilient materialhaving on two of the opposite sides thereofdownward ly-turned flanges partly surrounding the braces, and means for evaporating moisture from around said. structure, whereby cool air. may circulate around the liquid in receptacles on the shelf or shelves, substantially as described.

2. In a cooler for milk or other liquid, the combination of aAbottom pan supported by legs, inclined posts extending upwardly from said pan, cross braces interposed between and in line with the pairsof said posts'acting to brace the structure and as supports for shelves,

one or more removable shelves of resilient material having on two of the opposite sides thereof downwardly-turned, flanges partly surrounding the braces, and upwardly turned flanges on .the other two sides adapted torest against the adjacent posts, and means for evaporating moisture from around said struc-
